Cases chart, explained
CA's Blueprint for a Safer Economy assigns each county to a tier based on case rate and test positivity rate. What's opened / closed under each tier.
Tiers, from most severe to least severe, categorizes coronavirus spread as widespread; substantial; moderate; or minimal. Counties must stay in the current tier for 3 consecutive weeks and metrics from the last 2 consecutive weeks must fall into less restrictive tier before moving into a less restrictive tier.
We show only case charts labeled with each county's population-adjusted tier cut-offs.
